Abstract (en)

[origin: DE4408846C1] Method of producing a centring sleeve (1) in which a metallic supporting body (2) is provided with a polymer coating (4) on the inside at least in one section (3). The coating (4), at least at one end of its axial extension, is provided with a sealing lip (6) concentrically enclosing the axis (5). The supporting body is given a wall (7) by deep drawing of a material which can be cold worked. The wall (7) has a profile open in a U-shape in the axial direction, the profile being provided with the polymer coating (4) after it is produced and then being formed to size by a radial upset at the outside diameter (8) and/or a radial widening at the inside diameter (9). <IMAGE>
